There is sound coming from back of car with some fluid leakage

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Where is it you are seeing "fluid leakage"? Where does it show up? A "wobbling noise" sounds like it could be coming from the wheels of the vehicle. This could be due to a wheel bearing issue or a tire wear issue. Inspect the tires - is the tread appearing smooth and even? Or is it more like uneven wear, feathering, cupping or other bumpy tread patterns? If so, it can create noise. It is also an indication of suspension, steering or wheel alignment issues. If the tires look great, a technician should lift the vehicle and check the wheel spin for excessive resistance and noise from each wheel bearing. A worn bearing can make noise as it grinds away. It's all a guess though - you really need someone near you to hear the noise and see what to do with what's happening.
